Foreword

GB/T 6276 "industrial use - Determination of ammonium bicarbonate method" is divided into nine sections. --- Part 1. ammonium bicarbonate content of acid-base titration; --- Part 2. potentiometric titration of chloride content; --- Part 3. sulphide content Visible turbidimetric method; --- Part 4. sulphate content Visible turbidimetric method; --- Part 5. ash content by weight method; --- Part 6. iron content - Phenanthroline spectrophotometric method; --- Part 7. arsenic content diethyl dithiocarbamate silver spectrophotometry; --- Part 8. arsenic content Gutzeit method; --- Part 9. heavy metal content Visible turbidimetric method. This part of GB/T 86276 Part of. This standard replaces GB/T 6276.8-1986 "industrial use ammonium bicarbonate arsenic content Gutzeit method." This portion of the GB/T 6276.8-1986 The main differences are. --- Reagent solution, standard titration solution preparation and calibration methods such as the implementation of HG/T 2843 standard. This part is proposed by the China Petroleum and Chemical Industry Association. This part of the National Standardization Technical Committee centralized fertilizer and soil conditioner. This section drafted by. National Fertilizer Quality Supervision and Inspection Center (Shanghai). The main drafters of this section. Wang Ting, Zhong Wenyi. This section was first issued in 1986.
